.To `ALI. WH'OM IT. MAY 'OONOERNi Be it known that I, WILLIAM H. THOMAS, of Sacramento, inl the county of Sacramento, and Stateof California, have invented a new and improved Steam-Generator; andI do hereby declare .that the following is a full, clear, andexact description thereof, which will enable others skilled in, the art to make and use Vthe same, referencebeing had to the' accompanying drawings, forming part of this speciiication. I

This invention relates to a new and improved apparatus for heating'water and generating steam for various purposes; andthe invention consists in the arrangement of a steam or heating-coil withinaI submerged' furnace or :fire-box, in such a manner that the same can be connected with diercnt vessels, for various purposes, as for steaming, heating water forfbathgwashing, Snc.

y Figure lrepresen'ts a vertical central section. ofthe'heater, showing it connected witha. reservoir or vessel, and theifurnace surrounded by Water in a suitable tankv Figure 2 is across-section otgg. 1 through-the line :e w.-

Similar letters of reference "indicate corresponding parts.

A represents the Outer casinglor shell of the furnace. B is c coilspipe in the furnace, which,l at its upper end, is connected with theupper porticn'of a reservoir or-vessel in which it is desired to heat the water. The lower portion' of the vessel is connected withthe bottom or lower end of the'coiled tube B. It .will be seen.' that the water in the vessel will be heated by the circulation through the coil.

While the coil `islused for steaming purposes, theV condensed steam will pass down to the bottom o the coil, while the steam will be discharged -from the top, or through the upper pipe. Elastic hose-pipe is used in making these connections, so that steam or heated water may be carried to different vessels. without movingthe'furnace vif desired. l l

The furnace may be made portable, so as to adapt it to the various purposes fol-'which I design it. By submerging the iirehox., the shell isprotected from injury from the intense heat. C represents the grate of To supply the fuel with the necessary oxygen for its proper combustion, a current of air is admitted to and passed down uuderthelgratc through thejchannel D. n Y Y l I n ItY will be seen that the coil B is in contact with the burningv fuel, and exposed to the heated products ci' combustion its whole lcngth,'and thalnbeing thus exposed, the current of )rater which enters its 'lgwer end must` pass out as steam at its upper end, thus forming a most safer'and eiective medium forL thetransmission of heat, I

combined with a most economical expenditure of fuel.- l

E represents a water-tank, which is connected with the top of' the shell. F is the cap ofthe furnace, which sets over the top of the shell.r VGr is the chimney-pipe. his a. deiecting-plate,.which is attached to and hangs from the cap F, and which `extends down finto the tank E, which acts as a. spark-arrester.. The products of cornbustion, in their upwar'dpassage to the chimney-pipe G, impinge against `the plate z, and the sparks whichv strikevv the plate drop from it into the water, and are thereby extinguished, while the smoke passes under the plate and into the pipe G. i' i v Y i The fuel for the furnace is introduced through ,the cap F hyremoving the cover '.T. K represents the hose or water-pipe, -ivhiehis attached tothe upper end of the coil, and L the one-at the lower endl' Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-'- A steam-coil heating-furnace, submerged in vater, and supplied with air from the top, and provided witha tank, E, and dedector'h, all constructed and'arrauged substantially as herein shown and described.
